9k RPM
Hey guys I had my first ITR stolen about 1 year ago and i purchased a new ITR a month ago with a JDM ITR motor inside it and realized the ECU is a p28 chipped and its been running on obd1 for the past who knows how long.. so this car has been abused for sure even though everything on it is bone stock.
the rev limit on the ecu is 9200 rpm & yes I actually tested it out... but is a stock JDM ITR motor safe to rev to 8900-9000 RPM daily or will the rod bearings freak out on you?

first how did you test the limiter? if you used the tach its most likely not accurate.
second yes you can rev to 9k on stock motor but it will stress the rods/bolts/bearings/valvesprings that much more and accelerate wear. plus since you dont know the full history of the motor i wouldnt risk it. not only that but you have no idea what "tune" is on that chip. if you want to validate that tune hit up a dyno/tuner and see if the car is running safely. otherwise i would source a stock ecu until you can verify the tune on that chip.

could not agree more. You risk causing thousands of dollars of damage if you are driving a poorly tuned motor. Just let it sit until you find a reliable tuner to check it out for you man

Re: (ITR_cam)
mine will read well past 9 even with my stock ecu on it.
If you want to be sure you have a very close to stock tune, someone (like myself) could always burn you a new chip to use with a close to stock program.
I say that because since you have an obd1 ecu with a chip, it is impossible, no matter what other might say, that you can actually have / run a stock program. This is due to there never being an obd1 ITR motor and ecu.
